Abstract

Pulvérisation d'un liquide à l'aide d'un pulvérisateur. Le liquide est divisé en deux courants partiels Q1 , Q2 avant son entrée dans le pulvérisateur. Q1 est dirigé par un alésage axial dans le corps 1, puis une chambre de turbulence cylindrique 6. Q2 est superposé à Q1 par un orifice 12, perpendiculaire à l'axe et débouchant tangentiellement dans la chambre 6. Lé courant résultant traverse ensuite une chambre d'homogénéisation cylindrique 7, puis sort par une buse axiale 8, sous forme d'un jet à cône plein Le réglage du rapport Q1 /Q2 permet d'ajuster continûment l'angle du cône de pulvérisation entre 0 degrés et 70 degrés .
